It was a frantic weekend for employees at the Chengdu Research Base Of Panda Breeding in China last weekend as two different pandas gave birth to twins on the same day.

The two sets of twins make a total of nine cubs born at the base since the start of 2015.

Since opening, the base has been the birthplace for 165 cubs and has become the world’s largest panda breeding community. 144 giant pandas currently call the base home.

Panda cubs are blind at birth and weigh in at a tiny 150 grams. Born white, they develop their famous colouring later on.

Giant pandas are the rarest members of the bear family, with less than 2,000 pandas left in the wild. Listed as an endangered species, the giant pandas biggest threats are hunters, poachers and habitat loss.
